Boyfriend chose to go to USA?

We ve been together since late 2018. I always felt like I was his second option but ignored it

We decided to do a PhD and I planned to return to the UK to do my PhD there. He on the other hand didn't agree and was applying to US institutions, finally deciding to go to New York for his PhD.

I told him that LDR during PhD will be tough but he didn't agree and left for New York.

Why would he do this?
